A rival executive that had interest in Michael Pineda last offseason said his team had reservations due to the right-hander's second-half decline and his velocity drop. The Yankees were fully aware of both, which is why they required both X-rays and MRIs of both Pineda's elbow and shoulder and spoke with him before agreeing to their trade with the Mariners. All of the tests came back clean, New York general manager Brian Cashman said, but a pitcher's health never is guaranteed. Pineda either had an undetectable problem or was injured in spring training. He will undergo season-ending surgery Tuesday to repair a labrum tear in his shoulder.
